UNITED STATES JUDGE GREEN, OF CI'IATTANOOGA, TENNESSEE.

SAND RIDDLE.

Application filed August 2, 1923. Serial No. 655,295.

To all whom t may concern:

Be it known that I, JUDGE GREEN, a citi- Zen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain new and useful lmprovements in Sand Riddles; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has for its object the provision of a sifter which admits of the screen being readily removed from the fra-nie to be replaced by a screen of different mesh according to the nature of the material to be screened or sifted.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood fthat in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the applica-tion:

Figure i is a. top plan view of a riddle embodying the invention, parts being broken away,

Figure 2 is detail sectional view,

Figure 3 is an enlarged detail sectional view of the joint formed between the ends of the band and the parts associated therewith, and

Figure 4 is a detail view, the parts being separated.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The frame of the riddle comprises a band l and a hoop 2, said parts being reinforced at their outer edges, preferably by having a wire fitted thereto. The band 1 is split and is provided at its ends with angle. plates 3 which are riveted or otherwise secured f thereto, the offstanding elements of the angle plates being apertured to receive bolts 1.1L, whereby the band may be contracted so as to snugly embrace the hoop 2. A metal strip 5 is riveted or otherwise secured to the inner side of the band l adjacent the lower edge thereof and an edge portion is bent inwardly to provid@ a flange 6 which limits the downward move-ment of the hoop 2 and the screen 7. When the parts are assembled they are made secure by means of bolts 8 'which pass through corresponding openings formed in the angle plates 3, hoop 2 and band l. A protector and handle strap 9 covers the offstanding elements of the angle plates 3 and is retained in place by means of the bolts 8.

When the hoop. 2 is removed from the band l, a screen 7 of required mesh is fitted i to the lower edge thereof and when the parts are assembled, the edge portion of the screen 7 is confined between the band 1 and hoop 2, said screen'and hoop being supported upon the inner flange 6 of the strip 5. The band l is contracted by means of the bolts 4L so as" to clamp the hoop 2 and the edge portion of the screen 7 bent about the lower edge of the hoop and confined between the same and the band.

What is claimed is:

A riddle comprising a band having terminal offstanding portions, means coacting with the oifstanding terminal portions of the band whereby to contract the latter, a hoop within the band, a screen having an edge portion bent about the hoop and adapted to be clamped between the latter andthe band, means on the interior of the band to support the hoop and screen above the base of the band, a strap covering the offstanding terminal portions of the band and means securing said strap, band, hoop and screen together.

In testimony whereof I affix my rsignature in presence of two witnesses.

y.innen GREEN.
